<p>PURPOSE:To provide the toner which is improved in low-temp. fixability and offset resistance and is ameliorated in the roller staining of a fixing device. CONSTITUTION:This toner contains at least a resin and coloring agents. The region of <=5000mol.wt. in the mol.wt. distribution measured by GPC of the resin component is >=15% to <35% and the region of >=5,000,000mol.wt. is >=3%. The toner has a main peak in the region of 5,000 to 100,000mol.wt. and the acid value of the resin is 2 to 100mgKOH/g.</p> |
